Product FAQs
5 answersWhich panelboards are compatible with the HED41B040 circuit breaker?
This bolt-on branch breaker is designed for installation in Siemens P1, P2, and P3 panelboards, as well as SB switchboards.
Can the HED41B040 be used in DC electrical systems?
Yes, this breaker is rated for 125VDC applications and provides an interrupting capacity of 30kA at that voltage.
What wire sizes and materials are accepted by the lugs on this breaker?
The factory-installed lugs accept 10 AWG to 4 AWG copper (Cu) or aluminum (Al) conductors.
What is the difference between the HED4 and ED4 breaker series?
The HED4 series is the high-interrupting version of the standard ED4 frame. It offers higher short-circuit protection, such as a 25kAIC rating at 277VAC, for more demanding commercial and industrial applications.
What does the LI trip function mean on the HED41B040?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) protection against overloads and Instantaneous (I) protection against short circuits.
